During the credits, the producers thank the "University of Indiana" when it is actually "Indiana University" of which Alfred Kinsey was a part. The university notified director Bill Condon of the mistake. Condon gave his word that it would be taken care of when the film went on general release, but the mistake remains.
The chronology of the film suggests that the publication of a "new book" by Alfred Kinsey, The Origin of Higher Categories in Cynips, the appointment of Herman Wells as the president of Indiana University, and the showing of the "hygiene" film Know for Sure all occurred within a relatively short period of time. However, Kinsey published the book in question in 1935, Wells was not appointed as president until 1937 (interim) or 1938, and the film was not released until 1941.
